I got my new side folder Romanian all zeroed in real nice. After a few hours of shooting and a bump fire.. I go back to the range to check the if its still zeroed, its shifted way to the left. Is there any way to prevent the front sight drum from drifting left ot right, anyone else have this problem? This really pisses me off, I was thinking of somehow tacking the front sight drum down and going with a rear windage adj. site. Thanks, Perry |
Are you a safe craker?  I lived 10 years in East Mesa where are you at? I want to move back. Arizona is more gun friendly. Beautiful state. Thanks, Perry |

that is odd, I've never encountered that problem. I do believe that staking the front sight drum and throwing an RPK rear on it would be the easiest method, and make the rifle a whole lot easier to adjust to boot. I'm not a safe cracker, I just advocate "safe sex" and I'm in Tucson. |
Yeh, it sucks I spent two hours sighting it in because I didn't know drifting the cylinder one way made the zero go the opposite. I had it all nice at 50 yards, and then I took it out and shot it at a friends for those few hours, and then went to my local range and sighted my Aimpoint on the AR a little better, then I thought I would check the AK and it drifted to the left 8 inches, I looked at the drum and you could tell it went to the right further. To get it sighted it was already pretty far to the right. I am mad, I like the Aks but if they don't stay sighted in whats the point? I have another Romanian with a poly stock set. I could not get that front drum to budge, with a rubber mallet and punch. I ordered the front sight tool to see if thats gonna do it. If my other Ak gives me problems, I thinking about selling them and getting an 20" Hbar AR to use for a varmint gun. I already have the M4/A3 Bushy. Or I could just invest an a higher end US Ak? What are your thoughts? May I ask, how would I go about staking the front drum? |

you typically use a special punch and a hammer to stake, hell you could harden a nail to do it if you wish. basically you put a dimple in the metal in the front sight block near the edge drum's hole to spread the steel enough to hold the drum in place.(crappy description I know) with the other AK you might have to hit it with some penetrating oil, and once you move it it should be easily adjusted with the tool. and I've yet to have a problem with sights drifting like that on an AK, so dont give up hope just yet on the Kalashnikov. if you really want a super nice rifle you can always get an Arsenal Inc. those things are the absolute top of the line and are great shooters. |

Your's is the first post I'ver ever read about the front sight drum drfting. In some cases people have destroyed front sight tools trying to get it to move. Perhaps yours needs replacing. Like I said most have a hard time moving it. Okay, if it drifts it's either the drum or the sight base. If it's the drum, replace it. If it's the FSB, you can either replace that or maybe use Loc-tite that wicks. After zeroing the rifle apply the wicking Loc-tite to the drum. The Loc-tite will wick into any area around the drum and after it dries it will prevent the drum from shifting. |
The Loctite idea did cross my mind, I do have the red Loc-tite I used on the front sites of my Glock would that work? I try not to give up on the Ak so easy. I really noticed the hurt the Ak puts on a shoulder after shooting for a few hours, the AR15 is such a light recoiler. |

I've never heard of this either. I'd make sure that you have the problem properly diagnosed and if so, I 'd return it for replacement. I don't think that quick fixes for this are much of an alternative and may void whatever warranty you have. In any event, the manufacturer should straighten this out. |
At the factory when the rifle is sighted in a special punch is used to make a witness mark on the front sight and drum.  Doing this displaces metal on the front sight and the drum. The drum is bent ever so slightly and the hole in the front sight for the drum around the witness mark is ever so slightly out of round. This locks the the drum in place in the front sight. To fix the loose drum, You will need a hammer and a center punch. Push the drum all the way to one side. From the front of the front sight where the witness mark is use the center punch to put a couple of dimples on the oppsite side of the drum from the direction you pushed it. This will displace some metal so that when you push the drum back the other way to set the sights it will be tight in the front sight. To adjust the front sight, The first time you try moving the drum with a sight adjustmemt tool doesn't work because it is too tight for the amount of pushing force the tool applies to the drum. Use a brass punch on the drum and whop the crap out of it with a hammer. Check the witness mark and once you see the drum has moved the sight tool will usally work then. I had to set the sights on one Maadi ARM rifle that required me to pull a 3lb ball peen hammer out to get the drum to move. |
